The unit tests are now using a common base, which means that lib/dns/tests/ code now has to include lib/isc/include/isc/test.h and link with lib/isc/test.c and lib/ns/tests has to include both libisc and libdns parts. Instead of cross-linking code between the directories, move the /lib/<foo>/test.c to /tests/<foo>.c and /lib/<foo>/include/<foo>test.h to /tests/include/tests/<foo>.h and create a single libtest.la convenience library in /tests/. At the same time, move the /lib/<foo>/tests/ to /tests/<foo>/ (but keep it symlinked to the old location) and adjust paths accordingly. In few places, we are now using absolute paths instead of relative paths, because the directory level has changed. By moving the directories under the /tests/ directory, the test-related code is kept in a single place and we can avoid referencing files between libns->libdns->libisc which is unhealthy because they live in a separate Makefile-space. In the future, the /bin/tests/ should be merged to /tests/ and symlink kept, and the /fuzz/ directory moved to /tests/fuzz/.
